Hmmm, you're right, it does look like the sanitizer source code is closely tied to glibc. In sanitizer_common/sanitizer_allocator.cc I see direct references to __libc_malloc. In any case the step toward supporting the race detector with musl is going to start with porting the compiler-rt library to musl. If you just want to focus on Go, don't build the race detector. It looks like you are running the command `go install -v -race .`. Don't do that. To pass the tests you may need to modify the method tester.raceDetectorSupported in cmd/dist/test.go.
